T 0 all whomc't may concern.'

Be it known that I, WILLIAM E. P nNN,` a citizen of the United States, residing at Watertown, in thecounty of Jefferson and StateV of Visconsin, have invented certain new and useful Irriproveinentsr inV Butter-` Cutters, of which the following is a specification.

This invention relates toV apparatusqfor l means for securing and releasing the frame 20. i

that carries thecuttiiig wires.l y,

In theV accompanying drawings, Figure 1 is a front'elevation of a butter 'cutter emin jsection. Fig. 31s a fragmentary section throughone of the cylinders ina plane `4at right; angles Vto the sectional showing in Fi 2. y e

rIhe-Yapparatus is particularly intended for use inl creameries and -otherplaces wherey being n Y Y frigeratoi` in order lto hardenv the butter;

rlhe embodiment herein shown of, my yinj form, said -base supporting ya cylinder 2 and an oil reservoir Suitably supported above andcarried by the cylinder 2 'and the reserA voir 3 is Va Yrectangularframe 4 adapted to support abox a',-the bottomof vthe box `being removed before the box isfplaced upon thel frame 4. 5 is a Vrectangular frame `adapted to be supportedupon Athe open upper side of the box a, said frame carrying the'cutting wires 6. The fra'me'V is provided at oppor,-L

site endswith hooksf'adapted "to be engaged byeyesS on the upper ends of rods 9. 'The Y lower ends of the rods?)V pass freely through perforated lugs 170 formed uponja frame'11, said frame being pivotally connected Ato 4lugs In practice, the'b'utter, after it has` been worked, is packed in rectangular boxes a provided with, removable bottoms@ After filled,thejboxes are placed inthe re-l 12 on the frame 4. Nuts 91a' are turned upon the rodsQ'belowthelugs 10g On the pivoted frame 11 is a stud 13 that lies withiny the groove 14 of a cam 15, vsaid cam being pivoted at 16 to a bracketl? secured to the frame: 4. Tli'estud 13' projects through a guide-slot 18 in the bracket 17. Fixed to the Y specificati@ f LetterSPa'tent. Patented `J une 21,1921.`

cam 15 is a crank 19. It' will be seen that when the cam 15 is in the position shown in the drawings, the frame 5 is securely held in place upon the upper side of the box a, andV that when'the cam 15 ris swung to the left (as viewed in Fig. 1), the frame 11 is raised so that the Yeyes 8 may bedisengaged from tliehooks 7, thus permitting'of the. removal of the cutterframe 5.

' The butter mass within'the box rests upon 'a platen 20, and a hydraulic jack is preferably employed to raise and lower the platen within the box. SuchV j ack may be of any preferred i construction, as,'for example', that illustrated 'and describedV in my` copending 1914,"of which this application isa division. Herein I have deemed it unnecessary to illustrate and describe a hydraulicy jack in detail,v

and have shown vmerelya 'piston or plunger 21 mounted Vwithin the cylinderI 2 and ai-v ranged to 'be' actuated through the medium of two valved pistons 22 `operable in cylinders ated by theypistons 22.` A hand lever 25 isi i arranged to actuate the pistons 22' through the medium of a pivoted lever 26 and connecting rods'27.

is their oscillated to actuate the pistons 22 The hand leverA 25 bodying the features of my invention. Fig` application'Serial No. 844,618, filed June 12,

2 is a side view of themachine with paifts'j 23 to Vforce oil from'the'reservoir 3 intothe Y whereby tol cause the plunger 21 to rise, and,V

the'in'ovement is continued until the block of Abutter in the box a has been raisedto Vthedesired extent, the wires 6 `servingto cut' vthe block vertically -vduring such upwardy vmovement ofthe butter. When the butterA has been raised to thedesired poiiitthe operator takesY a cutter frame (not shown) containing a single cutting wire and draws CII 1 the platen in the desired position without said .frar'neacross the top of -tle'frame 5,

thereby slicing off that portion. vofthe block of butter which was cut by the wires 6. The prints thereby formed vare vremoved and the butter mass again` Vraised through operationV of the hand lever 25. After the entire mass of butter has been out into prints f the platen isV lowered into its original position. For this purpose Vthe pistons 222 are each provided with a stud 28 which, when ythe lever isswung out of its normal range of movement to an extreme position, engages 4with the corresponding -valve24 -to unseat it. 'In this position of thepi'stonboth ends of the bypass 38 are left open so that oilV may flowback -through the valve 24:- and bypassBSpermitting the piston Qlto descend. Thus it will be apparent that the hydraulic jack constitutes avery effective means for actuating the butter platen, for the reason that it may `be controlled solely through the manipulation of a single hand lever.'

Moreover, in the operation of vslicing off from the mass of butter within the boX, the portion Y which has been cut by the wires, the hy-V draulic jack 'serves 'to stationarily support the aid of any means especially designed to hold the platen against downward movement. y s ff Iy claim "as my invention: il.
